Abstract
In accordance with the invention, a solar rocking device comprises a pair of chambers coupled by a conduit, which assembly is pivotally mounted on a horizontal axis. Liquid partially fills the lower chamber above the conduit opening, and an absorber facilitates selective heating of the lower chamber. With sufficient heating, enough liquid is forced into the upper chamber to rotate the device, thereby reversing the positions of the chambers. The cycle repeats. Sunlight provides sufficient energy to rotate exemplary devices at least once every few minutes.
